To all whcmi my concern:

Be itknownthat I, linRniNANnMUM- MELTHEY, of Ocraopolis, Pennsylvania, have invented a new and useful Gas-Burner, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 'is a vertical section through one form. of burner embodying my invention; Fig. 2 is a vertical section through the Inixing chamber, on the line ll-l1 of Fig. 1; Fig. 3 is an end View of the flame deflector.

My invention relates to gas burners for heating furnaces and is designed to provide a cheap and efficient device, which is adapted oint.

The precise nature of my inven ion will'be best understood by reference to the accompan ing drawings, which will now be descri ed, it being premised, however, that chengescan be made 'in the details of construction herein shown and described In the drawings, the numeral '2 designates a nipple, having the contracted end 3 and the exteriorly screw threaded portion 4-, which projects through the tapped head 5, and 'is also provided with the jam nut 6.

The other end of this nipple 2 is connected in an manner to a as sup 1 i e.

Th2; head 5 is s cured lio d n end of T pipe-coupling 7 and projecting from the other end of this coupling is a pipe 8 which forms the mixing chamber for the air and gas the air entering through the pipe 9 which is connected to t e lower end of the coupling .7 and receiving its supply from any suitable source.

Projecting transverselythrough the mix a rod 10 haying a threaded 1 ortion 11 ext ding ee in the wall of the pipe 8 and also provided with a jam nut 12 to lockit in its adjusted position. U this shaft is the head 13 which is provided to rotate the shaft for the purpose herein after described. 'Securedto thisrod 10 and between the walls of the pipe 8 by means of the set screw 15 isa deflector 14. This olefiector is circular in v a cross section on a line with the rod 10 and Ward' the points-"16 and '17 p at the ends thereof.

As illustrated in the drawings the deof the outlet from the gas tube, a in the mixing cha gas tube toward and from the deflector, and. deflector transversely through a tapped ori Secured toth e" outer end of inlet, a mixing chamber, pointed the walls converge to;

tlector is located in the 8 and the jet of'gas coming from the nozzle 3 strikes the center of the point 16 andis equally deflected onflall sides'thcreof.

If it should he desired to in rease the heat on one sideo-f the burner the jam nut l-2- is released and the rod 11 is rotated in the proper direction to move the deflector away from the side requiring a greater amount of heat which will'direct a greaterportion of the air and gas mixture to that side, and the greater the movement of the deflector the greater the disproportion of the flame on each side thereof. By rotating the rod 10 a short distance the point of the deflector may be elevatedor lowered, to

wardly'.

The ad ustment of the burner 18 accomplished by advancing or retracting the threads 4 passing through the head 5.

The advantages of in invention result to supply the required amount to that part cular "part of the furnace, also, in, the simple and effective means for adjusting the burner, its cheapness and. simplicity of c0nstruction.

I claim:

center of thepipe deflect a greate i portion of the mixture upwardly or downnipple 2 through the medium of the screw-'1' YLVANIA, A CGRFORATIGN (IF 'PENNSTZL- "from the simple and e ective manner in which the gas nuxturecan be proportioned 1. A as burner having a mixingchamber,
